In a reply to the original post: My shrouds (new-to-me 2003 boat) are 14 feet 3/4 inch, near as dammit same as David Parker's.

David,
I haven't had the mast up yet 8-(. I think you should remove your bridle shackles and see how your (our) rig is. I'm hoping that with a ten hole adjuster on the forestay I can do Rick's trick and chuck the shroud adjusters and use shackles there. I'd do mine but:

1. Too cold.
2. Too much snow.
3. Boat is in bits underneath the deck.
4. Too cold.
5. The juniors are going to win the hockey tournament.
